Reaction constants for vacuum gas oil (VGO) hydrocracking and slurry phase hydroconversion of residues are calculated and positioned with respect to results from the literature. This perspective shows that results are well-correlated, despite a range of experimental set-ups and various feedstocks, author assumptions, and kinetic schemes being used. We observe that for vacuum residues (VR), slurry phase hydroconversion is essentially equivalent to thermal cracking with free radical production stabilized through hydrogenation reactions. This work also highlights the importance of catalyst type for conversion of heavy oils, identifies limitations in estimating kinetic parameters for the VGO lump in thermal cracking, and validates our results.

重油改质集总模型中的热裂解、加氢裂解和浆相加氢转化动力学参数综述

减压瓦斯油 (VGO) 加氢裂化和渣油浆相加氢转化的反应常数是根据文献结果计算和定位的。这一观点表明，尽管使用了一系列实验设置和各种原料、作者假设和动力学方案，但结果具有良好的相关性。我们观察到，对于减压渣油 (VR)，淤浆相加氢转化基本上等同于热裂解，通过加氢反应稳定自由基的产生。这项工作还强调了催化剂类型对重油转化的重要性，确定了估计热裂解中 VGO 块的动力学参数的局限性，并验证了我们的结果。
